CARD OR PAMPHLET HOLDING DEVICE.

Application filed August 5, 1925.

This invention relates tov improvements in card or pamphlet holdingmechanism. More particularly, the invention relates to devices of thatcharacter designed especially for use in connection with bread wrappingmachines for the purpose of delivering cards, or pain-- phlets, into thewrapping machine for enclosure within the wrapped loaves of bread.

It is the principal object of the present invention to provide a devicethat is an improvement over the device disclosed in my co-pendingapplication filed February 24, 19%, under Serial Number 695,751, and bymeans of which cards, or pamphlets, may be delivered, one at a time,onto the loaves of bread just prior to their being wrapped in that itmay be filled from the top and is designed for mounting outside of thewrapping machine whereas the other was inside.

Other objects of the invention reside in the various details ofconstruction and combination of parts as will hereinafter be describedwhich produces a more efficient and more easily handled mechanism.

In accomplishing the objects of the invention, I have provided theimproved details of construction, the preferred forms of which areillustrated in the accompanying drawings, wh-erein Figure 1 is a sideelevation of a card or pamphlet feeding device embodied by the presentinvention.

Figure 2 is a horizontal scc'ional view of the same taken on the line2-2 in Figure 1.

l igurc is a view of the device from the front end.

Figure 4: is a vertical section through the feeding device taken on theline 4-4 in Figure 1, showing the feed rollers and the adjustable cardstack supporting means.

The present device differs from the device of the co-pendingapplication, above mentioned, in that it is designed to feed the cardsor pamphlets fromthe bottom of the stack instead of from the top. Theadvantage of this resides in the fact that it may be refilled while thewrapping machine is in motion and not requiring any stopping of thebread feeding or wrapping mechanism as was necessary in the use of theother device.

The device, in its present construction, comprises a frame structureconsisting of four vertical posts 1 that are joined rigidly in spacedrelation by horizontal pieces 2 pro- Serial No. 48,235.

which two. parallel, spaced apart feed shafts 5 and 6 are rotatablyextended. The stack 3 is supported at its opposite edges just abovethese feed shafts by means of the inturned end portions 8 of verticalbars 9 that are located at opposite sides of the hopper and areadjustably fastened by set screws 10 to the horizontal pieces 2 so, thatthey may be adjusted to lower or raise the stack for the purpose ofvarying its distance above the feed rollers. The set screws extendthrough vertical slots 10 in the pieces 2 and are fixed at their innerends in the bars 9.

The feed shafts 5 and 6 are each equipped with a pair of feed rollers 11having flexible lingers 12 extended so as to wipe the lower end of thestack as the rollers revolve to thereby deliver the, pamphlets therefrominto a downwardly inclined chute 13 that is supported in the lower endof the frame. At their forward ends the two feed shafts are equipped, asshown in Figure 3, with int-ermeshing gears 15 and 16 of equal size sothat the shafts are caused to rotate at the same rate and in oppositedirections. The shaft 5 is extended at one end, as shown in Figures 1.and 2, and is operatively connected through gear sets 17 and 18 andshafts 19 and 20 with a gear 21 which operates in mesh with a gear 22that is fixed to a rotatable part of the wrapping mechanism with whichthe device is used. Through this mechanism the device is synchronizedwith the wrapping machine so that it will deliver one pamphlet or cardfor each loaf of bread delivered into the machine. The wrapping machinehas not been illustrated, but the loaves are delivered thereto, as shownin Figure 4, beneath the end of the chute 13.

The driving of the shafts 5 and 6 is such that the feed rollers turntoward each other at the top and the feed fingers 12 engage the bottompamphlet of the stack so as to draw its ends from the supports 8 andfold it downwardly between the feed rollers and shafts as shown inFigure 4.

In order to time the delivery of the pamphlets to the loaves of bread,as the latter are delivered into the wrapping; machine beneath thedischarge end of the chute 13, I have provided the stop or release lever25 which is pivotally supported by a pin 26 from a cross piece at andextends horizontally over the shaft 5 and is then turned laterally andhas a down-turned end 27 extended into the chute in. position to catchand retain the pamphlets delivered thereinto. A cam 29 is mounted on theshaft 5 and this operates the shaft revolves to engage with the lever tocause it to he lifted at the proper time to release the pamphlet or irdso that it will drop onto the loaf as the loaf passes beneath the lowerend of the delivery chute.

it is to he understood that the card feeding device may be mounted onthe wrapping machine in any suitable manner and may be driven by anysuitable mechanism, it being important only that the two machines besynchronized so that the pamphlets will be delivered into the wrappingmachine at the same rate as the articles to be wrapped are delivered.

rtssuming that the device is so constructed and that it is attachedproperly to the wrapping macl'iine for use, it is first tilled with asupply of cards or pamphlets which are stacked within the hopper and aresupported by the ends 8 of the bars 9; the latter being adjustedvertically so as to support the lower end of the stack at the properdistance from the feed rollers. lVhen the machine is in operation, thefingers 12 of the feed rollers engage the lower card of the stack witheach revolution and cause them to be fed into the hopper one at a timewhere they are retained temporarily by the end of the lever. The cam 9.8is properly set on the shaft 5 to engage and lift the lever to releasethe pamphlets as the loaves are delivered beneath the end of the chuteso that a card will be delivered onto each loaf just before the wrapperis applied.

The device may be easily filled and does not require that the machine bestopped for this purpose.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters-Patent, is:

1. A device of the character described, comprising a frame structureprovided at its lower end with a delivery chute, a pair of feed shaftsextended in parallel relation and in the same horizontal plane throughsaid frame, friction feed rollers on said shafts, a pair of verticallyadjustable bars within the frame at opposite sides and having inturnedends adapted to support a stack of pamphlets from their opposite edgesjust aeove the shafts, and means for rotating the shafts at the samerate and in opposite directions to cause the feed rollers to engage withthe bottom of the stack to feed the pamphlets therefrom down ardlybetween the shafts into the chute.

2. A device as in claim 1 provided with means operable by the rotationof one of the feed shafts for timing the delivery of the pamphlets fromthe chute.

A. device of the character described, comprising a frame structureprovided at its lower end with a delivery chute, a pair of feed shaftsextended in parallel relation and in the same horizontal plane throughsaid frame, friction feed rollers on said shafts, a pair of verticallyadjustable bars within the frame at opposite sides and having int-urnedends a stack of pamphlets edges just above the shafts, and means forrotating the shafts at the same rate and in opposite directions to causethe feed rollers to engage with the bottom of the stack to feed thepamphlets therefrom downwardly between the shafts into the chute, alever pivotally fixed to the frame overlying one of the feed shafts andhaving an end portion extended in the path of delivery of pamphlets fromthe chute and a cam on the shaft operable to lift the lever to releasethe pamphlets for delivery.
